Provided are an inhibitor, a prophylactic, and a therapeutic agent for rheumatoid arthritis that have no side effects and that can correct immune abnormality associated with rheumatoid arthritis. The inhibitor, the prophylactic, and the agent for rheumatoid arthritis contain a-derived material as an active ingredient. The inhibitor, the prophylactic and the agent are used as an antirheumatic drug for controlling the activity of rheumatoid arthritis by alleviating immune abnormality associated with rheumatoid arthritis. The inhibitor, the prophylactic, and the agent are also used for a living individual who has not been definitively diagnosed with rheumatoid arthritis. The inhibitor, the prophylactic, and the agent are continuously administered to the living individual from any point before definitive diagnosis of rheumatoid arthritis to any point after the definitive diagnosis. The-derived material is at least one material selected from the group includingalgae, paramylon derived from the, water-soluble amorphous paramylon prepared by treating the paramylon with alkali and neutralizing the treated paramylon, and emulsion paramylon prepared by ejecting a solution of the paramylon from a narrow bore nozzle at a very high pressure to cause the solution to collide with a collision surface.

Provided are a novel renal failure progression inhibitor, prophylactic agent for renal failure, and indoxyl sulfate production inhibitor, intended for human use, in particular, for a patient with renal failure. The renal failure progression inhibitor, prophylactic agent for renal failure, and indoxyl sulfate production inhibitor each comprises paramylon derived fromor a processed product thereof as an active ingredient. In the case of the renal failure progression inhibitor, for example, paramylon is continuously orally administered to a patient suffering from chronic renal failure, undergoing a dialysis therapy, several times per day in a dose of 1 to 5 g per intake. In particular, the renal failure progression inhibitor is singly administered to the patient in a capsule or powdered preparation at a prescribed time interval before and after administration of other drugs.

Renal insufficiency progression inhibitor, prophylactic agent for renal insufficiency and indoxyl sulfate production inhibitor

Provided are a prophylactic or therapeutic agent for a peptic ulcer, a food additive for prevention and treatment of a peptic ulcer, an iNOS expression inhibitor, and a COX-2 expression inhibitor, all of which have little side effects. The prophylactic or therapeutic agent contains a-derived material as an active ingredient. The-derived material may be, paramylon, or an acid-treated paramylon. The prophylactic or therapeutic agent is useful for the prevention or treatment of a peptic ulcer induced by psychological stress. The peptic ulcer may be a gastric ulcer. The food additive contains a-derived material as an active ingredient.

Prophylactic or therapeutic agent for peptic ulcer, food additive for prophylactic or therapeutic use, iNOS expression inhibitor and COX-2 expression inhibitor

An algae culture method capable of efficiently producing an osmotic pressure adjusting substance, a production method of the substance, and an algae culture method for recovering carbon dioxide from a mixed gas containing carbon dioxide and sulfurous acid gas. The methods involve preparing a plurality of enrichment cultures each containing betaine by culturing a culture of microalgae derived from an environmental specimen under a photoautotrophic condition and under a plurality of culture conditions; making a cultivation plan in which an optimum enrichment culture suitable for a main culture is selected from the plurality of enrichment cultures; producing a main culture that contains betaine under the photoautotrophic condition and a salt concentration of 10 wt. % or more; and separating betaine. In the main culture, the algae containing betaine are cultured while the mixed gas containing sulfurous acid gas and carbon dioxide is blown to a culture solution of the algae.
